I have a low beam out on my sig. bulb is fine, it is getting current to the plug (* tested with multi-meter*) swapped bulbs still on pass side, high beams work all around, low beam works on drivers side (even with bulb from pass side) no trouble codes, no "bulb out" light, no check engine light. i am completely stumped called the stealership, they want 109 to reflash everything, and to check it, i told them my symptoms and they said "well i dont know you will have to bring it in" he said he didnt think it would be the tipm if its only one, and it may be a bad plug. i mean im at a loss, the plugs good because its getting current on both high and low, the bulb is good and no "check" lights what could this be?
I had no low beams.previous owner told me it started the same way.one headlight then the other then signals then brake lights.i fixed everything this weekend tipm fixed headlights.then I had to get tail light circuit boards.Then I replaced about 10 bulbs that were fried.
reflash or new tipm, when the other goes i guess ill worry but i havent fragged a bulb up front yet, had issues with the rear but re organized the bulbs and they work fine
thats what i thought, the DA's at the dealer here dont know anything but "we'll hook it up and see" anyway to do a manual reflash
